Is this the best birthday surprise EVER? The heartwarming moment a son SHOCKS his mum by telling her his fiancee is expecting

THIS video is seriously heartwarming.

This is the heartwarming, emotional moment son Ashley gives his mum the ultimate birthday present- by announcing she is going to be a grandma.

He broke the news in a truly novel way- by setting up a camera pretending to just want to get a family photo, before taking off his jumper off to reveal his red t-shirt that says 'This guy is going to be a daddy'.

"Do you like my t-shirt?" he asks his unsuspecting mum cheekily.

When the message finally sinks in, his mum is in absolute shock. "Are you joking?" she asks, before adding, "I'm going to pass out!"

The family share an emotional hug as his mum breaks down into happy sobs.

In an online message, the 36-year-old wrote his mother was desperate to be a gran.

'But this news came as a complete shock to them both, they genuinely were not expecting it at all,' he wrote.

The son met his partner Alexandra, from Sweden, five years ago and became engaged back in March after Ashley proposed by Central Park in New York.
